Steel latticed shell-concrete core tube structure system and construction method

The invention discloses a steel reticulated shell-concrete core tube structure system and a construction method, the steel reticulated shell-concrete core tube structure system comprises a concrete core tube and a steel reticulated shell, the steel reticulated shell sleeves the outer side of the concrete core tube, and a plurality of horizontal steel beams are uniformly mounted between the outer wall of the concrete core tube and the steel reticulated shell; structural floor slabs are fixed between the adjacent horizontal steel beams through studs. The invention relates to the technical field of civil engineering structures. The steel reticulated shell-concrete core tube structural system provided by the invention has the advantages that the building special-shaped curved surface external facade modeling requirement is met, the integration of the structural system and a curtain wall system is realized, no additional structural vertical component is added, no structural column is arranged in a building use spa
